Foil 47 HLA/RTI versus HPF/MPI

From Overview of Integration of Databases and Distributed Objects with the Web Tutorial: ITEA HPCC Conference Aberdeen Md. -- July 13 98. by Geoffrey Fox, Nancy McCracken


1 We can support any given paradigm at either high functionality (web server) or high performance (backend) level
2 HPCC Messaging could be a Java/RMI middle tier MPI or Nexus/Optimized Machine specific MPI at backend
3 JWORB supports CORBA based RTI already and we can bridge to high performance event driven simulation systems like SPEEDES at the high performance backend layer
4 However most problems can be thought of a set of coarse grain entities which are internally data parallel but the coarse grain structure is "functional" parallelism
5 So HLA/RTI is especially natural as tier 2 management level of these coarse entities
6 Entities can be time synchronized simulations and use MPI(HPF?) at either middle or back end tier or in fact as in DMSO simulations a federate running a custom discrete event simulation
